Abstract (en)

Thermally writable composition comprises white or light-colored mixture containing iron(III)- or molybdenum(VI) compounds (reactant A), phenols having at least two hydroxy groups (reactant B), a compound fusible at 70-150[deg] C, and a binding agent. Independent claims are also included for: (1) a thermally writable recording material comprising a carrier substrate and thermally writable composition, where the thermally writable composition is applied to the surface of the carrier substrate, and dried; and (2) producing the thermally writable recording material, comprising acidifying the carrier substrate, encapsulating at least one of the reactants, or applying an intermediate coating with barrier properties on a basic or neutral paper.
